Delay-Tolerant Networking (DTN) technology enables the nodes of an underwater acoustic network to communicate under conditions of frequent link disruptions and in networks topologies, in which end-to-end connections may never be available. Our implementation was based on the DTN2 open-source project, which represents a reference implementation of the DTN protocols and is designed as an experimental...
Power Line Carrier communication is a fast-developing technology and finds many applications, such as automatic meter-reading system. However, as the one-hop communication distance is limited due to the channel attenuation and strong line noises, relay technology is necessary for PLC networking. Among all the relay methods, Ant Colony Algorithm is a promising one but still with some shortcomings,...
In DTNs, due to the unique characteristic of frequent partitioning, multicasting is a considerably different and challenging problem. Moreover, the single data multicast is different from multiple data multicast. In this paper, The mathematics model of multiple data multicast for DTNs is established, and the ant colony optimization algorithm introduce to solve the multiple data multicast problem....
In this work we deal with the problem of dynamic decentralized self-optimization of forwarding protocols in delay-tolerant networks. We consider the two-hop forwarding protocol and we model the routing problem as an optimization one. We describe, under mild assumptions on the contact process among mobile nodes, the connection between the number of copies of a message and the cumulative probability...
When two administratively independent domains need to engage in cooperation of some kind, some initial common known point of contact must exist, both in terms of the application topological position (i.e., IP address, transport protocol and port) and in terms of the interface technology (e.g., the protocol suite of the interaction). In a world of many domains of many types (not necessarily autonomous...
Many problems in sensor networks can be formulated as optimization problems. Existing distributed optimization algorithms typically rely on choosing a step size to ensure convergence. In this case, the communication between sensor nodes occurs each time the computations are carried out. Since in sensor networks, the energy required for communication can be significantly greater than the energy required...
Internet Relay Chat (IRC) is a critical application in military networks for maintaining situational awareness and conducting battle management at all echelons. But these networks are often subject to frequent disconnections, limited bandwidth, and long delays, especially when using satellite services and field radios. Such conditions are inhospitable to TCP, and thus the standard IRC protocol, which...
